Application filed December 23, 1914. Serial No. 878,722.

To all whom it may concern:

Be it known that I, :MINARD A. PQSSONS, a citizen of the United States,residlng at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certam new and useful Im rovements in Gas-Ranges, of which thefolibwing is a specificatlon, reference being had therein to theaccompanying drawing.

My invention relates to improvements 1n gas ranges.

The object of my invention is to provide a gas range in which a broilerburner is arranged in the upper portion of the oven and whereby a damperis so arranged that it is open when the gas supply to the broller burneris open and closed when the gas supply to the broiler burner is closed.This is essential owing to the fact that in broihng it is necessary tohave some escape for the smoke and when it is also necessary to close upthe oven when baking, which result follows from the structure hereinlater described.

Another object of my invention is to provide a simple and effectivearrangement having certain details of structure and combination of partshereinafter fully described.

In the accompanying drawings, Figure 1 is a perspective view, in dottedlines, of the upper end of an oven showing my improvement appliedthereto. Fig. 2 is a side elevation, partly broken away, showlng thearrangement of the gas valve for the broiler burner and the gas valvefor the baking burner. Fig. 3 is a perspective view of a gas ovensimilar to that shown in Fig. 1, but showing the lock between the gasvalve for the broiler burner and the gas valve for the baking burner,whereby but one burner can be used at a time. Fig. 4 is an en.- largedside elevation of Fig. 1, showing the oven in section. Fig. 5 is aperspective view of my improved damper.

Referring now to the drawings, 1 represents the oven which has arrangedadjacent its upper end the broiler burner 2, which is supplied with gasthrough the pipe 3 leading from the valve 4. This valve 4 is of theturning-plug type having the plug 5 provided with a handle 6 at itsouter end and by means of which the gas is turned on and ofi" to thebroiler burner 2. The oven 1, to the rear just above the broiler burner2, is provided with an opening7, provided with a Specification ofLetters lPatent.

l 1 ISSUED guide-Way 8 on which is slidably mounted the damper 9. Thisdamper is preferably of sheet metal having a series of openings 10,adapted to register with corresponding openlngs in the oven, whereby theproper ventilation for the escape of the smoke for the upper end of theoven is provided. Secured to the enlarged portion 11 of the damper 9 isa rod 12, which extends outwardly and is provided with an eye 13, at itsouter end on the outside of the oven. The side of the oven adjacent thesaid rod is provided with brackets 14 and 15, in which is mounted theoscillating rod 16, which has at its outer end the bracket 14 anddownwardly turned portion 17. This portion 17 enters the eye 13 and byoscillating the rod 16, the rod 12 is oscillated for opening and closingthe damper 9.

The end of the rod 16 on the outside of the bracket 15 is provided witha downwardly turned portion 18, which is connected to the curved arm 19by means of a cotter-pin 20. The turning plug 5 of the valve 4 isprovided with a rigidly extending arm 21, to which the lower end of thelink 19 is connected by the cotter-pin 22. By this arrangement it willbe seen that the turning of the plug 5 to the left by means of thehandle 6 to open the valve allows the gas to pass through the pipe 3 tothe broiler burner, throws the arm 21 upwardly and through the medium ofthe link 19, the rod 16 is rocked. This rockingof the rod 16 through themedium of the rod 12 causes the damper 9 to move in a position so thatthe openings 10 register with the openings in the rear wall of the oven,whereby the smoke and the like may pass from the oven. In stoves of thischaracter it is very essential that this damper be closed when thebaking burner isin operation and in order to facilitate this, I haveprovided the structure above mentioned. In ovens of this character it isalso very essential that the broiler burner be out of operation when thebaking burner is in operation, for the reason that it often happens thatthe gas is turned on to the broiler burner" and is not ignited, and whenthe baking burner is lighted there occurs an explosion in the oven. Inorder to prevent the two burners from being turned on at the same time,I have provided the structure shown in Figs. 3 and 4.

The valve 23 for supplying the gas to the baking burner has its turningplug 24 extended outwardly and provided with a and 27, and on the insideof these ears, is

provided with an enlarged portion 28. Surrounding this enlarged portionis an elongated plate member 29, having a circular opening 30 withinwhich turns the member 28. Extending upwardly within the plate 29 is anelongated slot 31, which communicates with the circular opening 30.Connected to the upper end of the plate 29 is a rod 32, which has itsupper end-connected by a cotter pin 33to a rigid arm 84, carried by theturning plug 5 of the broiler burner.

When the turning plug 24 of the baking burner is turned in a position tosupply gas to the said baking burner, the enlarged portion 28 carriedthereby is in a position transverse the enlarged circular openings 30,and locks the rod 32 against movement. Thus it will be seen that theturning plug 5 of the broiler burner cannot be operated and thus gascannot be supplied to the broiler burner when the valve of the bakingburner is open. Whenthe valve of the baking burner is turned, theenlarged portion 28 carried by the turning plug 2-1 registers with theelongated slot 31 and thus the turning plug 5 can be turned as the plate29 travels downwardly around the member.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. The combination with an oven having a bakingburner, a gas supply valve for said burner, a broiler burner in theoven, a gas supply valve for the broiler burner, a damper in the oven,and means operated by the gas supply valve of the broiler burner foropening the damper when the valve is open and closing the damper beforethe valve for the baking burner is opened.

2. The combination with an oven, of a baking burner in the lower end ofthe oven, a broiler burner in the upper end of the oven, gas supplyvalves for said burners, a damper for the oven, and means operated bythe gas supply valve of the broiler burner for opening the damper whenthe valve is open and closing the damper before the valve of the bakingburner is opened.

3. The combination with a gas oven having a baking burner in its lowerend, a gas supply valve for said burner, a broiler burner in the upperend of the oven, a gas supply valve for the broiler burner, a damper forthe oven, and means connecting the gas supply valve of the broilerburner and the damper, whereby the damper is opened when the broilerburner valve is open and closed before the valve of the baking burner isopened.

4. The combination with a gas range having a baking burner in its lowerend, a gas supply valve for said burner, a broiler burner in the upperend of the oven, a gas supply valve for the broiler burner, a damper forthe oven, means operated by the movement of the gas supply valve of thebroiler burner for opening the damper when the valve is opened andclosing the damper when the valve is closed, and means connecting thetwo valves whereby but one valve is allowed to be opened at the sametime.
